Well before I start - just in case the gurus are reading - I'm really excited about StrangerVille. Can't wait to move my family in there!!!
Anyway, Selvadorada seems very South or Central American to me. We do not have an Asian world, but we already have SO MUCH Asian decor. If we got an Asian world, I think it would come with even more Asian objects, which I just don't think we need.

This wasn't an option, but I would also LOVE to see a Middle-Eastern inspired world. With mosque-looking buildings. I'm not even sure if this would be possible but this

would be really cool in game.
